My wife had to send her ipad away to be repaired so we backed up the game before it went away. It's been returned and we've loaded from a back up, and her mystery manor level is still where it was and her collections the same - just as we had hoped.

However when she selects GIFTS FRIENDS or WALL a pop up box appears saying that 'You are not Registered'. Everything else is fine, quests, rooms, etc, and I can visit her from my ipad.
